Great simple Coral ring in 10K gold. The band is stamped 18 and 10K. So I tested the metal and it is 10K yellow gold. The Coral is a nice deep red color. The ring is size 7 1/8. Weight is 3.0 grms. The top measures approx. 5/8". Condition is excellent. I would date this fine ring at c1950's-70's. This ring can be re-sized my any good jeweler who works with antique and vintage jewelry.
